Frequently Asked Questions

Quick answers to the most common questions about psiLynx.

Checks & Quotas

What counts as one check?

Each URL × platform combination counts as one check. Checking 10 URLs on both Mobile and Desktop uses 20 checks. Accuracy Mode multiplies this by the number of runs (e.g. ×3).

When does my weekly quota reset?

Quotas reset every 7 days from the date you subscribed. The exact reset date is shown on the Subscription & Billing page and in the quota bar on the project page.

What happens if I exceed my quota?

You cannot start a new check run if it would exceed your remaining quota. The confirmation dialog shows the projected cost before you confirm. Scheduled checks are skipped (Skipped quota) when the quota is exhausted.

Can I re-run only the URLs that failed?

Yes. After a check completes with errors, a Repeat failed button appears. Re-running failed URLs does not consume quota for the URLs that already succeeded. The same option is available via Retry failed in Batch History.

Data & Results

How long is check history kept?

History retention depends on your plan. The exact limits are shown on the Plans & Pricing page.

What is the difference between Lab Data and Field Data (CrUX)?

Lab Data comes from Lighthouse checks run by psiLynx — controlled, repeatable measurements made on demand. Field Data (CrUX) comes from real Chrome users visiting your site, aggregated by Google. Field data reflects actual user experience but requires sufficient traffic to populate.

Why is there no Field Data for my URL?

Google's Chrome UX Report only includes URLs with sufficient real-user traffic. Low-traffic pages, staging environments, and recently launched pages typically won't have CrUX data. An explanatory card is shown in place of the metrics when data is unavailable.

How often is Field Data (CrUX) updated?

psiLynx collects CrUX data automatically once a week.

Reports & Sharing

Do share links expire?

No — share links do not expire on their own. A link becomes invalid only if the report is deleted. See Sharing Reports for details.

Can I export raw data?

Yes, on all plans including Free. Use Export CSV in Batch History to download a spreadsheet with all check results. See Report Detail for the full list of exportable fields.

Plans & Billing

Is a credit card required to get started?

No. The Free plan starts immediately with no payment information required. You can upgrade to a paid plan at any time from the Plans page.

What happens when I hit my weekly check limit?

Checks stop until the quota resets on Monday. You'll receive an email warning at 80% usage. Upgrading your plan applies the new limit immediately — no need to wait for reset.

Can I switch between plans?

Yes. Go to Plans & Pricing and select the new plan. Stripe handles proration automatically.

Team & Access

Can team members see billing information?

No. Only the account owner can access billing and subscription settings. Team members — including Admins — cannot view or manage billing.

What happens to a team member's work if I remove them?

Removing a member revokes their access immediately. All data they interacted with (projects, reports, URLs) remains in your account.

Uptime Monitoring

What is the DEGRADED status?

DEGRADED means the server returned HTTP 200 but the page size dropped more than 50% below the baseline recorded on the first successful check. This typically indicates a maintenance page or a deployment issue that doesn't return an error code.

How many monitors can I have per project?

Up to 5 monitors per project. Each URL can only have one monitor.
